Managing blood sugar levels, it is very easy. If you are checking your blood sugar levels, if you are finding it is 100, it is very normal. Upto 70 it is normal blood sugar. Anything less than 70 is low sugar and anything 50, it needs a medical help. So if you are on insulin, try to reduce the insulin dosage of that day and immediately consult your diabetologist to control your insulin dosage. Or if you are on oral hypoglycemics agents like tablets for your diabetes, better you go and visit your diabetologist or that he can decrease the tablet dosage and the blood sugar levels will be in the normal range.
